Application filed March 20, 1917. Serial No, 156,202.

specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a vertegraph or machine for producing a graph of the bony structures of the body.

It will be understood by those skilled in the art that the position the bones of the backoccupy with respect to each other determines certain pathological conditions of the system, and physicians make use of this fact incorrecting such conditions by pressure or percussion upon the mal-alined bones.

This apparatus is intended to provide a record of the condition. of the bones of the back whereby the patient may himself observe the position of the mal-alined bones, one graph showing the adjustment in one plane while the other graph will show the lateral mal-alinements. 7

Another object of the invention is to provide means whereby the apparatus may be adjustedfor persons of greater or less size as may be convenient, the tracing apparatus normally operating in a given position.

Another object of the invention is to provide a tracing board forthe support of the paper upon which the tracing ismade which may beturned 90 degrees thereby producing on the same sheet of paper two tracings, one of which will show lateral mal-alinements and the other posterior or anterior malalinements of the bones.

It will of course be clear that any animal might have the position of its bones delineated with this machine, although the apparatus is more especially adapted for use with the human body, and is capable of producing a graph thereof in any position the body may assume.

Other objects of the invention'will appear as the description proceeds.

An embodiment of the invention is shown in the drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that-there may be many modifications thereof.

Figure 1 is a side elevation of the complete apparatus,

Fig. 2 is a plan view of the complete apparatus,

Fig. 3 is an end elevation of the complete apparatus.

Fig. 1 is a detail view of one of the table legs showing the slot through which the operating frame is raised and lowered, there being one of said slots in each of the table legs,

Fig. 5 1s an end view of the table showing the means for raising and lowerlng the table, and also showing the means for making the diagram with the sheet to be marked held in a vertical position, a portion of the frame being broken away,

Fig. 6 is a view in elevation of the marker used for showing I lateral deviations when the paper to be marked is held in the horizontal position, and

Fig. 7 is a view of the marking apparatus shown in Fig. 6, looking from the right Fig. 6.

The apparatus comprises a table having four legs 1, 2, 3 and 4, which legs are suitably. connected with cross pieces 5 and side pieces 6 and 7, the top 8 being placed thereon to receive the patient. The legs 1 to 4 inclusive are hollow to receive posts, 9 to 12 inclusive, of the frame which supports the tracing apparatus. Each of the posts 9 to 12 inclusive has'a link 13 at its lower end pivotally connected thereto and connected with levers 14 or 15 as the case may be, there being two of'said levers at each end of the table. Each of the levers rests upon a pin 16 carried by a bracket 17 supported by the transverse end members 5, which hold the legs together. The two levers 1 1 and 15 are pivotally connected'together at one end, and are connected with a vertically exten.d ing notched plate 18, the object being to provide means whereby the posts 9 to 12 and rectangular frame 13' carried at the top of said post may beadjusted in height, the notches in the plate 18 engaging a screw 0r bolt 19 to hold said posts and the frame connected therewith at different levels. When the frame and tracing apparatus carried thereby has been moved to the desired level, it is secured inthat position by means of the set screws 17, 18, 19 and 20. The frame at the top of the posts 9 to 12 'inelusive comprises two cross bars 13, and two longitudinal bars 20 and 21 connecting the two-bars 13. Depending from the longitudinal extending bars are two arms 23 and 24 at each side of the frame, and said arms 1 form a support for a rod 25 at each side of? the frame, which rod extends from one end to the other thereof, and which are connectedwith the end posts by means of screws 26' and 27. Each of the rods 25 is provided with a tubular slide 28, and said tubular slides are connected by means of two transversely extending rods 29 and 30'. The rod 30 is provided with a Y shaped yoke having 7 two arms 31 and 32 at the ends of which is provided, said screw enabling the arm 37 to be adjusted with respect to the yoke which supports it, said yoke having two projecting lugs 40 and 41 at its lower end for the support of the pivot pin 42 carrying the arm 37.

7 At the lower end of the yoke there is a rigid tubular arm 43, within which slides a rod 44 connected at its outer end to a tubular sleeve 45. A spring 46 surrounds the rod 44 and tends to hold the sleeve 45 upright. A rod 47 is rigidly connected with the sleeve 45 and pivotally connected at 48 with the yoke lug 41, A rod 49 is also loosely connected with the sleeve 55 and loosely connected with a ring 50 on the sleeve 35. A rod 52 7 passes loosely through the sleeve 45 and it scribed 1s as follows :Assum1ng a erson to :lie upon the-table in the position shown in has a pencil or stylus 53 at its lower end, said rod also passing through sleeves 54 and 55,- the former connected with a weight56 and'the latter at the top of a cross arm 57 carried by'the-rod'58 extending upwardly from theiweight 56. The cross arm 57 carries loosely an arm 59 which has a small weight60 at oneend thereof and which arm bears upon the top ofthe rod 52, the object being to hold the pencil 53 in contact with the paper on-the board 62. The board 62 is pivotally mounted on bolts 63 and 64 which passthrough the end posts 9. and 12, jointed links 65,66, 67 and 68 holding the board whenin the horizontal position shown in Fig. 3. The spring 36 tends to hold the yoke arms up off the body on the table 8 while a spring 69 tends to pull slides 28, to the left hand end of the machine, see Fig. 1; the

object beingto reduce the pressure required to push the slides along when the apparatus isin use. r

The operation oftheapparatus just de- Fig.1, the pointer 38 is moved along the median line of: the backbone, and as the pointer moves along, the slides 28 will move When it is desired to take a graph of the 3 interior or posterior positions of the several bones of the spine,the table 62 is turned up to the position in which it is shown in Fig. 5, the rod 47 is disengaged from the rod 44 and is raised up to the dotted position shown at 47, the rod 49 is disengaged from the-pencil carrying sleeve 55 and the pin 44 is removed from the end of the rod 44 and tube 43 in which it is slidable thereby allowing the rod 44 to move longitudinally under the action of the spiral spring surrounding it. The rod 44 then has a pencil applied at its end, and as said pencil is moved along the paper fastened on the board 62 it makes a mark which corresponds to the several positions of the back bone proc- V a person in the normal standing position, i 7

the mal-alinements in both planes being equally well taken.

Having thus described my invention, what I claim as new and desireto secure by Letters Patent of the United States, is as follows, express reservation being made of per missible modifications.
